    Hi all,

    I have multiple issues in the few months with V5, and I an trying to downgrade to V4, preferrably 3.2.22 to check.

    I understand that the 5-to-4 downgrade is problematic and I follow the instructions from here:
    http://en.miui.com/thread-3319-1-1.html

    However, I can flash JLB3, JLB7, any v5 rom, etc. correctly, but when I try to flash any 3.1.x or 3.2.x ROM, the phone gets stuck in the boot process (white MI forever)

    I am using MIFlash through fastboot to flash.

    My phone is Mi2 32Gb

    Thanks

    Thanks leggy.

    But can you please post the link to the wiui version - It's all in chinese (which unfortunately I can't read) and seems that nothing happens when I press what seems to be the link.

    Is the 3.2.22 you linked in anyway different from the usual 3.2.22 ? different kernel ?

    Thank you,

    I will try in a few days.

    I'm now trying QDT14. It's so and so. Had some crashes. We'll see.

    I've run into the same problem. Was using a MIUI V4 rom, decided to finally try a V5 rom, didn't like it and wanted to revert back. I followed Wajk's instructions and made sure to flash JLB 3.0 first before flashing a V4 rom, but now I'm stuck on the white Mi logo with no way to boot or get into recovery mode.

    Will have to wait until I get home to see if I can fix this via MiFlash.

    Miflash can get you out of this, but not into v4 rom.

    Nice, I figured that would be the case. Thanks for the heads up.

    I guess I'll just have to deal with V5 for now. It seems all the "new" features and add-ons in V5 are all fluff. I found V4 to be more polished.

    True. V5 is unreliable and would be considered somewhere between alpha and beta by normal standards.

    Unfortunately, the closed source policy of Xiaomi makes sure that the problems will continue for a long time. In addition there are many baseband issues courtesy of Qualcomm.

    I should try the methods above to reload a v4 version, but nowadays I am testing the QDT14 plain android version.

    If I decide to give downgrading another shot (and am successful), I will let you know.

    very easy ,use the boot.img in the v5 to replace that one in the v4. this is very important .
    and then use the recovery to downgrade v5 to v4.

    According to this: http://en.miui.com/thread-1885-1-2.html

    IMPORTANT : Once you updated to QDT07/JLB14/3.3.29 Then you can't downgrade to earlier versionsof V5 or V4.

    If true, that is bad news.....

    In step 2 do you mean to enable True Dual Boot? Why?
